本文介绍了一个使用Java实现XML绑定的示例，包括定义Student和Classroom类，并通过JAXB进行序列化和反序列化操作。

Student.java

package com.conv.xml;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Student {
	private String id;
	private String name;
	private String sex;
	private int age;
	private Classroom classroom;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
	public Classroom getClassroom() {
		return classroom;
	}
	public void setClassroom(Classroom classroom) {
		this.classroom = classroom;
	}
	public Student() {
		super();
	}
	public Student(String id, String name, String sex, int age,
			Classroom classroom) {
		super();
		this.id = id;
		this.name = name;
		this.sex = sex;
		this.age = age;
		this.classroom = classroom;
	}
	
}

Classroom.java

package com.conv.xml;

public class Classroom {
	private String id;
	private String name;
	private String grade;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getGrade() {
		return grade;
	}
	public void setGrade(String grade) {
		this.grade = grade;
	}
	public Classroom(String id, String name, String grade) {
		super();
		this.id = id;
		this.name = name;
		this.grade = grade;
	}
	public Classroom() {
		super();
	}
}

测试类：

package com.conv.xml;

import java.io.StringReader;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

public class Test {
	@org.junit.Test
	public void test1(){
		try {
			JAXBContext context = JAXBContext.newInstance(Student.class);
			Marshaller marshaller = context.createMarshaller();
			Student stu = new Student("1","zhangsan","男",25,new Classroom("1","计071-2","2011"));
			marshaller.marshal(stu, System.out);
		} catch (JAXBException e) {
			e.printStackTrace();
		}
	}
	
	@org.junit.Test
	public void test2(){
		String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><student><age>25</age><classroom><grade>2011</grade><id>1</id><name>计071-2</name></classroom><id>1</id><name>zhangsan</name><sex>男</sex></student>";
		try {
			JAXBContext context = JAXBContext.newInstance(Student.class);
			Unmarshaller unmarshaller = context.createUnmarshaller();
			Student stu = (Student)unmarshaller.unmarshal(new StringReader(xml));
			System.out.println("name:"+stu.getName()+"   className:"+stu.getClassroom().getName());
		} catch (JAXBException e) {
			e.printStackTrace();
		}
	}
}

使用了JUNIT进行测试。
